Function

The tool changer was designed to work entirely through mechanical interaction. There is only one source of motion, which is a double acting air cylinder. The pneumatic drawbar also uses one small air cylinder. You must have a source of compressed air (appx. 80psi or better) to use the tool changer. The interface with your CNC is simply one digital bit of I/O. By simply turning the cylinder ON and OFF you execute one toolchange cycle. There are no complicated electronics or PLC required!!!

Only one digital bit of I/O required (on/off signal)

Rapid Tool Change (1 to 3 seconds)
